Specification of Letters Patent.

Patented Jan. 18, 1910.

Application filed July 13, 1908. Serial No. 443,189.

To all whom it may concern:

Be it known that I, CHARLns E. SIMPSON, residing at Portsmouth, in the county of Scioto and State of Ohio, have invented certain new and useful Improvements in Brick lte- Presses, of which the following is a specification.

My invention relates to certain new and useful improvements in machines used in the manufacturing of brick, the brick being first formed into the required shape and partly dried, after which, in their semi-dried condition, they are placed in my machine and repressed to eliminate minor defects and inequalities.

Generically, my invention embodies a. machine including a suitable supporting frame, a die holder to receive the brick die, a removable top therefor .and a plunger to engage the brick in the die and compress the same, together with means for first bringing the top over the die, then into engagement with the die, and means for moving the plunger into the die to press the brick.y

My invention also includes means for removing the top from the die when the brick has been compressed and other means for ejecting the brick from the die.

In its more subordinate features my improved invention has for its object to provide a hand power brick repress which can be manufactured at a minimum expense, be of lightweight, and at the same time readily and effectively serve its intended purposes.

More specifically, my invention embodies those novel details of construction, combination and arrangement of parts all of which will be first described in detail, and then be specifically pointed out in the appended claims, reference being had to the accompanying drawings, in which Figure 1, is a perspective view of my invention showing the parts in their initial position. Fig. 2, is a central vertical longitudinal section thereof, the parts being in their second position in dotted lines, and in their third position in full lines. Fig. 3, is a. similar view showing the parts in their nal compressing position. Fig. 1, is a central vertical longitudinal section showing the parts in their brick ejecting position. Fig. 5, is a cross section on the line 5-5 of Fig. 2. Fig. 6, is a horizontal section on the line (3-6 of Fig. 2. Fig. 7, is an enlarged detail view of a portion of my invention. Fig. 8, is a detail rear elevation of a part of my invention. Fig. 9, is a detail view of a part of my invention.

Referring now to the accompanying drawings, in which like letters and numerals of reference indicate like parts in all of the gures, 1 designates the sides of the frame which are spaced apart and joined together by bolts 1a, the' bolts 1a4 being of angular cross section and terminating in threaded reduced ends that project through the sides 1 and receive the nuts 1b.

The sides 1 have bearings 1'3 to receive the shafts 21--3l on which the sleeves 2b--3b are respectively mounted. The sleeve 2b receives the hub 2c of a lever 2, while the sleeve 3b receives the hub 3C of a second lever 3, the hubs 20--3c being keyed to their respective sleeves. The sleeves 2b-3b extend the full width between the sides 1 1. The levers 2 and 3 and the hubs 21-32, however, are of less width than the space between the sides 1 1, as clearly indicated in Fig. 8 of the drawings. The levers 2 and 3 each have a plane 2de-3d terminating in a shoulder 2e-3e, the shoulders 2"'--3e and the planes 21--3d facing one another. The lower lever 3 has a saddle 3f for a purpose presently to appear. The sides 1-1 at the top haveinwardly projecting lugs 1d to which the die is bolted, the die 50 having an open top and bottom.

13 designates a xed guide having a V- shaped slideway 1f to coperate with the slide 25a of a piston 25. The piston 25 also has another V-shaped slide 25b which operates in the slideway 24a of an adjustable bearing block 24 that is mounted in a sup port 1g on the inner face of one side 1. The block is adjusted to take up wear by the headed set screws 24D and is held in the support 1g by a bolt 24C that passes through an elongated slot 24d in the block 24 and through ears in the support 1g. A block or false bottom 25 rests on the piston 25 and fits snugly within the die 50 to form a bottom therefor, the block 25'3 acting as a piston head, as it were. While I have shown the piston 25 as provided with apertures 25c in the drawings, yet such apertures may be omitted, if desired.

25d represents a steel bearing knob held with its shank in an aperture in the lower end of the piston 25, by a set screw 25X, so as to rest on the similar knob 2f that is carried by the lever 2. A U-shaped iron hook member 10 is secured to the lever 2, and at times engages the cross members 1 to limit the movement of the lever 2 in its downward direction. A rod 5, having a head 5a, serves t0 operate the levers 2 and 3. The head 5a has a pair of opposite planes .5b-5b, forming a wedge, the planes 56h-5" merging with stops 5C to guide the plates 29-2e to limit the movement of the anti-friction rollers G-G that are interposed between the head 5a and the levers 2 and 3, respectively.

7 designates a shaft operable by a lever 7x and journaled in a suitable bearing in the frame sides 1. The shaft 7 has a tri-grooved sheave S keyed thereto. An equalizer bar 9 is pivotally secured to the rod 5, as at 5X, to the ends of which bar, chains Sla-9a are secured. The chains 9a-95L pass around the outer grooves Sn-Sa of the sheave S and are secured to the sheave drum at their ends. A third chain 9b is secured in the middle groove 8b of the sheave 8 and is fastened to a rod that passes through a lug 5d on the rod and is provided with a buffer spring and an adjusting nut 5. On its upper surface the rod 5 has an inclined portion 5C to cooperate with a ianged roller 11 that is keyed to a hollow sleeve 11a which turns on a stationary shaft 11b that is held in the arms 11C. The arms 11C are pivoted at 11d to bracket irons 11' on the sides 1. The roller 11 is pressed against the rod 5 by buffer springs 12, as indicated in FiO'. 2.

113 designates a shaft mounted in bearings 1m on the sides 1 and susceptible of up and down as well as rotary motion. The shaft 113 is supported by springs 14 that are secured to the laterally projected ears 16au of a plate 1G secured to the top of the lever 2 and the springs 1st carry hooks 15 that enter the sockets 13a in the shaft 113. Therefore the shaft 113 is supported from the lever 2. The saddle 3f of the lever 3 rests on the shaft 113. The ends of the shaft. 113 project beyond the sides 1 and have apertures 13x to receive the ends 17x of the arms 17, nuts 17y being secured to such ends to hold the arms to the shaft. The arms 17 are joined at their upper ends by a bridge 18 that carries the top plate 19 for the mold 50, a grip member 18a being provided so that the arms 17 may be swung into their various positions.

2O designates stops carried by the sides 1 for limiting the movement of the arms 17.

21 represents a hollow shaft mounted on a rod 21a that is secured to the side plates of the frame and on which hollow shaft 21, the double groove sheave 22 is mounted, the sheave 22 serving to receive the chain 23 that is secured to the piston 25, at one end and at the other end it is secured to the sheave 22 so that the chain 23 will be received by one groove of the sheave 22, s indicated.

24 represents a second chain secured to the sheave 22 and susceptible of being wound in the other groove of the sheave and the chain 24 is connected with a treadle lever 26 through the medium of a swivel connection 27. The treadle lever 2G is formed of two pieces of strap iron 2(5-26C pivoted on a rod 2Gd secured to the side plates 1 of the frame. The irons 26 are bent toward one another and merged into one, after which they are bent to the outside of the machine and receive the foot pedal 26e, as shown in the drawings. It should be stated that the weight of the piston 25 is sutlicient to hold the pedal in its normal position with the piston in the posit-ion shown in Fig. 2, of the drawings.

In order to protect the vital part-s from dust and dirt and the like, I provide a pair of side plates 2S whose rear ends are bent at right angles, as at 23a and secured by a rod 28b that passes therethrough and through the side plates 1a. The plates 28 rest against the sides of the levers 2 and 3. At their front ends the plates 28 are joined by a transverse plate 28d and are provided with notched portions 2SC to receive a rod 23e on which the plates 28 are hung at their front ends. The lever 2 carries a cap plate 29 which has pendent flanges to pass over the plates 28 and 28h, as clearly shown in Fig. 41, of the drawings.

29X designates a protecting hood for the projecting portion of the rod 5 and its cooperating parts, the hood 29 being shown in Fig. 2 of the drawings, and omitted in Fig. 1, to more clearly show the construction of applicants invention.

30 designates arms pivotally secured at 30a to the side plates 1 1 of the machine. The side plates 1 haveY legs 1n and are mounted also on wheels 1W so that the machine may be readily transported from place to place.

So far as described, the manner in which my invention operates will be best eX- plained, as follows: Assume the parts to be in the position shown in Fig. 1, the operator places the brick to be re-pressed into the die 50, after which he grasps the handle and moves the top plate over the die 59 into the position shown in dotted lines in Fig. 2. He then grasps the lever 7 X and moves it in the direction of the arrow in Fig. 1, causing the shaft 7 to be rotated and thereby move the rod is the direction of the arrow in Fig. 2. This causes the levers 2 and 3 to be forced relatively apart, the lever 3 moving in the direction of the arrow in Fig. 2 and the lever 2 tending to move in the direction of its arrow in Fig. 2. The weight of the members together with the tension of the springs 14 is sufficient to prevent any movement of the lever 2 until the top plate 19 is brought into contact with the die 50, as shown in full lines in Fig. 2, of the drawings, after which, the further movement of the rod 5 in the direc-tion of the arrow 2 willfcause the leveil 2 to be moved in the direction of its arrow in Fig. 2, to the position shown in F ig. 3, to compress the brick B. The operator then reverses the movement of the lever 7X. The chain then pulls the rod 5 in a direction opposite to the arrow in Fig. 2, permitting the lever 2 and piston 25 to fall toward its original position until the hook 10 engages the rod 1a. The lever 2, however, cannot drop any farther. The springs 14; are strong enough to raise the arms 17, bridge 18 and cap plate 19, back to the position shown in dotted lines in Fig. 2, after which, the operator swings the top off the die 50 back to the position shown in Fig. 1. pedal plate 26C of the treadle 26, drawing down on the chain 9A- to turn the sheave 22 to raise the piston 25 to the position shown in F ig. at, and eject the brick from the mold. After which, the operator releases the treadle 2G, when the weight of the piston 25 will return the parts to their normal position.

The principal advantage this press has over those in common use is that a great part of friction is eliminated by using rollers to take up the strain when pressure is applied, and the moving parts are so arranged, that, as they wear they sett-le to the worn position and remain there; the reverse motion of the lever does not throw the worn bearings to the opposite side of the journals, as do the presses now in common use. As the rollers do not pass the pivot ends of the levers 2 and 3 they will always exert the proper thrust on the levers 2 and 3. It will also be further seen that the vital parts of the machine are fully protected from dust etc. so that the operating parts will not become clogged and rendered inoperative.

F rom the foregoing description, taken in connection with the accompanying drawings, it is thought that the complete construction, operation and advantages of my invention will be readily understood by those skilled in the art to which the invention appertains.
